Maybe a YMMV, since few folks are reporting not able to see this offer.

Fine Print:

Enrollment for the offer is limited. Limit 1 statement credit per American Express Card across all American Express offer channels. Statement credit will appear on your billing statement within 8 weeks after American Express receives information from the merchant about your qualifying purchase. Note that American Express may not receive information about your qualifying purchase from the merchant until all of the items from your qualifying purchase have been provided or shipped by the merchant. Statement credit may be reversed if qualifying purchase is returned/cancelled. If American Express does not receive information that identifies your transaction as qualifying for the offer, you will not receive the statement credit. For example, your transaction will not qualify if: (i) the merchant uses a mobile or wireless card reader to process it; (ii) it is made with an electronic wallet or through a third party; or (iii) it is not made directly with the merchant. Program Terms and Conditions apply; see below for details. Click the 'Add to Card' button and use your synced American Express® Card to redeem this offer today!

Here's an idea. Buy a $100 Costco card. Go into a Costco, use the Costco Gift card to buy 2 $50 CPK Gift cards for 80 bucks. Then use a combination of the CPK gift card and your AMEX when you go to CPK next time and you will get the 10 dollars back as long as you put 25 dollars of your CPK bill on your AMEX. #Discountdoubledeal

OP should probably add some mention of Costco.com to the title of the thread. I had no idea it was related to Costco until opening it. Luckily I have a synced card and got the offer so $25 off for me is great! Thanks!!

This offer and the CPK offer were not appearing for me, even when I clicked the 'Load more offers' button at the bottom. After scrolling through all the deals, I decided to re-sync my card, so from the bottom of the page click on 'Unsync my Card' to remove your card, then follow the instructions to sync that same card again. After doing this, the Costco and CPK deal are now available for me.
